Beit known that I, WILLIAM G. GROSS, of

Boston, Massachusetts, have invented certain new and. useful Improvements y in` vlllachinery Myinvention Ais `an improvement on that kindof folding-machine shown andzdescribed 1881. It has reference to the devices for carrying in Letters Patent No. 240,390, dated April 19,

y the` successive sheets to propery place upon the `folding-table; to a combination 4of instrumen talities intended to adapt thefmachine to the needs of that method oi' folding, now used to .t sheets, which are rstpastedftogether' along their vertical central line of fold, and are then folded as onesheet;` and to a device'which may be used asa suhstitutefor the `continuous coni- 1 )cal-roll, andiwhich, although in a broad sense the equivalent of that roll, nevertheless possesses novel characteristics.; A l l The nature of my invention andthe manner `in whichthe samejs or may be carriedinto effect can best be explained and understood by reference to theaccompanying drawings, in

` "j place until the following sheet. is danseressen position which they ,assumewhen;` the second sheet is brought above the first. 4is a plan with the tape-carrying` rollers removed.`

Roll-D in this instance is one of a 'pair of rol-ls, D D', supposed to bev thel delivery-rol1s of aprinting-press. The.` crossbars areplacedatfsuitable intervals apar-t, so `that asjtheycome raround enchn turn vwill meet thesheet just in rear of the point whereit is to bese'vered from the 'sheet infront by the cated lilu Fig. 1, where '.firepresents the sheet.

Some newspapers`,'as is well -knownreonsist' ploy, in'conjunc'tion with the tuckingfblade, a.

1 is'driven bvmechahism oflrnown 'constrnctioin` use va vihratory tricher-blade, F, ot. ordinary construction, which can be timed and arranged of :twoY- or more supe'rposed separate sheets,

which are pasted together along the line ou'.

which the leaves of 'the paper open, and are thenfolded.-l i l In order to adapt -my-xnachiue for such pti` `pers,Iadopt the following arrangement: -Iemvbratorypower-driven lpanter-blade, G, which similar to thatused for the tucker-blade,but

Vhas not sd great ran ge or extent of movement j as the latter blade.' This paster-blade draws its supplyot` paste from anysuitable sourcelas, for instance,- fro'n1 'a paste-box, H, with the '4 while thfsheet that follows it travels forward concave bottom -of which the convex face of t35 theA blade is ncontact. The blademoves for an instant just far enough back to uncover in front ofitsedge arslit, e, in the bottom ot' the box, through which paste oozes, and is` taken up'and carried along'onthe edge of the blade 4 as 'the latterv moves forward.4

' In order to hold in position the `under sheet and cornes into place above it,` I make use of two parsof .nippers, I, one pair on each side ot' the table in. a position to grasp the opposite *sides ofthesheet, and the two nippers of each "pair onopposite sides of the opening. a in the ingwiper-cam vdriven from @any coxwenient-A 'foldingt'ablm as .indicated in Fig. 7. The' nipf-pwb'ffar arrangedto project up through-the 3i', et

spring (not shown) is rotated in-'adirection to cause-the nippers to'be swung down'below the face lof theftable,and the shaft is provided with a crank-ann and s tud, (indicated by dotted lines 1n: Fig. 8,) which, by a suitable rotat-v part of the machine, Iis operated to cause the u ippers .to rise and close upon the paper sheetf yatltln'a ppertitiiei Springahdcam controlled mp'pers o r yclaiii'ps of thisdeseritien arewellknown devices',-particularly in the dit towhich :ny-invention pertaius, and requiren 'lrther description-heren T he parte' thus far described are timed ,in their movementsjsdas to tio-operate'ind-.litrloh emma.

-In orderto tuck the papier down into the' eStores- 11pm andammo avec 'fas .Indicated in Fig.I 8.". The'- nippe'r's ot' each painare mounted on a rockshaft,.which by a` lowing manner: The first sheet, e', is broughtl 'l by the'carrier along to""its-proper v position on the folding-table, severed 'from the sheet in rear pdste-blade descends and .tucks the 'sheet down -into the opening enough to cause 1t to enter the bite of the foldin grolls,

' and along the line of contact between itsedge and the paper sheet. Before the paster can rise in" so doing delivers paste andthentlropped. At this nstantvthg a a'sbort distance, not far 'the clamps or nippers, vwhich before were retracted, will have been projected from.the tab le and upon the opposite edges of the paper,

-which they clamp, as seen in liig.n 7, at points adjoining but on opposite sides'of the edges l ofthe slot a. v- Theythus hold the sheet a?, with its pasted middleportion tucked down and out of the' way, while the sheet in' rear moves along and-comesdirectly over sheet w. When .y this takes place sheetw' is disengaged from thecarrier,and simultaneously the nippers release' their hold 'andthe tucking-bladeF descends and first tucks the central part or the,

upper sheet down iutocontact with the already depressed and pasted part ofthe under sheet,

by which operation -the two sheets are stuck I together, and then, by continuing its downward movement, tucks the two togethcrinto the bite of the' folding-rolls, by. vwhich they 'aref operated on as onesheet inthe usual way.

'It is manifest that three or more sheets may be pasted together, as well as two. 1t', for instance, there should bethree sheets, the pesterblade would move twice-once foreach of the first two sheets-and the tochter-blade would operate only on the third lsheet, and so on.

ICC

The nippers in such `case would be arranged' 'to movefso as to release the sheet below, and then at once return to clamp the two'ishe'ets,

and so on' until' the final sheet should come, at lwhich time they would finally quit the sheets.-

In the event'of folding only singlesheets the paster-blade can readily' be thrown out of engagement and the tucker-blade speeded so as to increase its rate of vibration to the needed extent. i 1' The vin'strurnentalities which take -and fold the sheet or sheets tucked down by the blade Fmay be similar to those described in Lettersjv Patent No.240,390,1iereinbefore referred to.

`the equivalent therefor, I can make' use of ap -pliances whichpI now proceed Vto describe.

These'appliances are represented in the placeY ,in vibrate soas .to move the cross-pini to andii'ay from the legs of the fork, as will In lien, however, of using conical rol l s, and as.

K, and are shownmore clearly in-Figs. 9,10, il. a.

.z as above stated, and are placedv opposite-one:

,another in a horizontalfiplane, with the pointi V'presently beidescribed: I have 'not deemed it necessary to show the camarran gement inthhiv 4figure nor in Fig. 10,which representsa some#` what similar appliance.l Such 4an.arrangement lswell known in the art andreqnires nore'xplanation. Thewheels K are powerfdriven,

at which they are incontactin .the 'same` horizont-aL-plane with the poi'nt where.interests-4 pin `i extends across ythe legs of the fork. The

l. .shafts on which the'wheelsfare carried are 4 mounted `in and project laterallyfrom Atheside,- of thel'rame' opposite vto thatfrom which fthe holder J projects. andthe distance between the two parts J- K is'about equal'the llength 'ot' the conicalrollsavhoseplaee they take.`

The wheelsfK' represent the bases of such rolls land the pin z the point where theaxes'ot' the two rolls would intersect it' prolonged. Tin-ir relative arrangementis-clearly shown in Figs.`

2, 4, and also in Fig. 11, inwliich-latter tigure I have represented the manner in which they act to turn the folded sheet, which may be,

explained as follows: The 'cocker-blade acts to double the sheet or sheets along the line of fold and to tuck it down into the bite of the wheels K and between the legs of theforked har-f, from which thecross-pin i at this time is withdrawn. VImmediately thereafter` thc cross-pin, by the action of its cani, is moved so as tot pass through the bar ffar enough to perfora-te aud-hold thelower corner the holder. The shcet,.while turning, enters the pocket S, (similar to the iikc-lettered contrivance in Letters Patent No. 240,39U,) and,

by a tricher-blade, J', working through an opening, s, in said pocket, is tucked between the conical rolls I', which makethe second fold. It is then taken in tur'n by the third set, K', and fourth set, M of rolls, by which it is folded in substantially the manner set forth in the aforesaid Letters Patent. L and It are thetuckers, which operate i connection with the twol sets ofrolls last above mentioned. ln lieu of the forked bar f and crosspin i, l-Ycan employ a .holders'nch as repre sented in Fig. 10. This consists ofA a stationary leg, 1, and a leg, 2, pivoted thereto and acted on by a cam at the time and'in the manner substantially* as hereinbefore described with relation to arm h. 0n a stud projectingr from the stationary leg is loosely mounted a disk, 3, and on a stiid projecting from the interior opposite face of the movable leg is similarly mounted a disk, 4, between which and the leg is.interposed a spring, 5, which pushes the disk out towardthe opposite disk, 3. The

r sheet wotpaper is held between `the disks in fend of the machine.

thefmanner indicated in ythe figaro, arid lthey latter arecaused to-intermittentlyandat; the proper times clamp and' release the sheet.

In "orderv to facilitate.` the' turning ofthe 1 yshcetrat. the time the first fold is made, I make use cfa pair ot' power-driventurning-wheels,

l0, speededso as tomove at the same :rate at which the sheet:travels, nnd placed at :apoiut intermediate between the [irst and second set of folding-rolls, as'indicated in Figs .1 andi). The axes'orshafts oftil'ewheclsare set at anV inclination, as shown, and so that their -prolongation Vwill pass through the point at which the sheet isA held by theV holder J. The peripheries of the wheelsaretapered' sojas to Iconstitute frusta ot coneswhose apez'resare at 'the same po1nt,.J By means of .their] appli ances the sheet is carried` surely into proper position. "The wheels are placedfa't such a distancefrom' the Vpoint J that f the sheet `iqnits themjby'the timeit reaches the .p o Vsition. `in which'it is' readyltobc acted on by the' tncker J'. They can, of course, b c used as well in connection withycouical rollsas with thedevices J K, as indicated in .FigI 12, in

which l h ave represented diag'rammat'ically a folding-machine adapted to receive and fold two newspapers at once, the newspapers trav eling side by side from the pressb to -proper place upon the foldingtablc, as indicated at a: X. All vthat` is needed is to place the folding'- rolls on one side ot' the machine, which operate on one paper,in a position exactly the' reverse ot' that occupied by those on theotherfside of the machine, which operate on thco'ther paper, as indicated inthe figure. The twosctsof conical rolls P l' K' and P' lz K2 being set with `their smaller ends pointing inwardly, the

smaller, .P and P', revolve inthe sameadirection, but l' K' revolve in direction'oppositeto l2 K2, respectively, as indicated by thearrow, as do also the two sets M N M( N' of cylindrical rolls, which make the tinal folds. The reason for this arrangement is that the one paper is discharged from one nd'of the' machine and the other paper from the opposite Assuming the end-ofthe machine represented in the drawings to be the` rio bis

rear end, the papewa` passes .down between I' rolls P in front of rolls 1',- and thence rearwardly' through rolls-l' K' and M lPaper X, on the contrary, passes down from between rolls P in rear ot' rolls I, and thence toward the front end of the machine through I2 K2 and M' N'. This arrangement of two sets 'of conical foldingrolls, permitting the mode ot' operation just'.` described, is convenientand compact', an saves both room and expense.

Having described my improvements, what l claim as new and ot' my invention isfl. Theendless tapes, the rolls for supporting and driving the same, the pinor brad armed [30' bars carried by said tapes', and the strippers for disengaging the sheets from said brads, in combination with theslotted foldingtable and the'tuckenblade for tueking the sheet down through the slot in said table, these parts being :zo and the tucker, these parts being arranged land arranged and operated and'timed inY their' 5; The'lho'hlderJ and wheels K, in combiua- Y2v5l movements'relativelylto onejanother substantially as and for the purposes hereinbeforeset forth'.1
